Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00637 | $0.00637 |
| Opus 5 | $0.00318 | $0.00318 |
| Sonnet 5 | $0.00127 | $0.00127 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
tracecat-mcp-community CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tracecat MCP Server - Development Guide
Architecture
src/
├── index.ts # Entry point - starts StdioTransport immediately
├── server.ts # Creates McpServer and registers all tools
├── client.ts # HTTP client with lazy init (login on first call)
├── types.ts # TypeScript interfaces
└── tools/ # One file per domain (12 files, 52 tools)
Auth
- Tracecat uses session cookies (
fastapiusersauth), not API keys - Login via
POST /auth/login(form-urlencoded) - Client uses lazy init:
ensureInitialized()inrequest()— no login at startup
Build & Run
npm install
npm run build # tsc
node dist/index.js # run directly
npm run dev # watch mode with tsx

API Quirks
workspace_idmust be a query param, not a header- Action/Secret/Schedule updates use POST, not PATCH (but workflow update uses PATCH)
- Action
inputsmust be a YAML string, not JSON - Actions list:
GET /actions?workflow_id=...(not nested under workflows) - Graph operations use optimistic locking (
base_version) - Empty responses (204/no body) are returned as
{ success: true }— handles delete operations gracefully
API Endpoints Reference
Key endpoints verified against OpenAPI spec:
| Operation | Endpoint | Notes |
|---|---|---|
| Run workflow | POST /workflow-executions |
Body: { workflow_id, inputs } |
| Run draft | POST /workflow-executions/draft |
Same body, uses uncommitted version |
| Get webhook | GET /workflows/{id}/webhook |
Returns URL, status, secret |
| Toggle webhook | PATCH /workflows/{id}/webhook |
Body: { status: "online"/"offline" } |
| Search secrets | GET /secrets/search |
Requires environment query param |
| Update secret | POST /secrets/{id} |
Body: SecretUpdate schema |
| Schedule interval | POST /schedules |
every uses ISO 8601 duration (PT5M), NOT 5m |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
